st: time dummy variables with streg

[Daniel Simon <dhs29@cornell.edu>]

Hi - I'm estimating a hazard model with streg. I believe that some of the 
covariates, as well as the hazard rate, may be correlated with the passage 
of calendar time.  Is there any problem with including year dummy variables 
in a hazard model? Specifically, I'm estimating a log-normal 
model.  Thanks. Daniel
